WINDOW MECHANISM.

Patented Dec. 25., 1906.

Application filed November 9, 1905. Serial No. 286,606.

To all whom it ntay concern.-

Be it known that I, MORRIS PARKER HEN- VIS, a citizen of the UnitedStates, residing at Norfolk, in the county of Norfolk and State ofVirginia, have invented certain'new and useful Improvements in WVindowMechanisms, of which the following is a specification.

My invention relates to window mechanisms for cars, steamboats, and thelike.

The object of the invention is to provide means for raising and loweringthe windows.

Further objects and advantages will be more fully understood by havingrecourse to 1 the accompanying drawings, forming a part of thisspecification, in which Figure 1 is a cross-sectional view taken on theline 1 in Fig. 2. Fig. 2 is a front or in; side view, one side beingremoved to show the mechanism. Fig. 3 is a plan of the U shapedspring-ended rod. Fig. 4 is a side view of the same and is anenlargement of that shown in Fig. 1. Fig. 5 is a side view of a modifiedform of spring-ended rod. Fig. 6 is a part front view of the window andits frame, showing the springs inserted in the side of the frame whenthe windows are provided with transoms. Fig. 7 is a plan of thecounterbalance-weight. Fig. 8 is a perspective view of the elevator baror carrier. Fig. 9 is a side view of one end of the counterbalance-weight, showing a part sectional elevation setting out the modeof fastening the suspending-ropes thereto.

In the drawings like reference-numerals indicate similar parts in allthe views.

1 and 2 are the side and bottom boards of the housing, respectively.

3 is the window-sill, having a sloping outer portion, as shown.

4 is the window-frame, and 4 is the top portion thereof, upon which theroof rests in the ordinary manner.

5 is the window-sash provided with glass and may be with or withouttransoms.

6 is a bar or bead placed on the outside of the sash at an angle, asshown in Fig. 1, and is for the purpose of forming a stop against whichthe sash bears when closed. 7 is a similar bead or bar on the inside ofthe sash and is for preventing the sash from being pulled toofarinwardly when the window is to be opened. 8, Fig. 1, is a slot orelongated opening slightly longer than the width of the sash 5 I and ofsuch size as to permit the sash to be lowered in it, as shown by thedotted lines in Figs. 1 and 2.

9 is an elevator bar or carrier normally in the position as indicated inFigs. 1 and 2, but when the sash is pulled inward the lower part of thesash 5 rests upon the bar and when the window is lowered it pushes thebar down ward and subsequently causes the window to ascend automaticallyby a weight when a certain spring is released, as will be hereinafterdescribed. The bar or carrier is guided in a vertical position by meansof the vertical bars or beading 10, secured at some convenient pointbelow the window-sill 3. v

1 1 is a counterbalance-weight and is adapted to balance the weight ofthe bar 9 and the window when it is to be raised and lowered; but'whenthe window is closed, as shown in Figs. 1 and 2, the weight keeps thebar 9 close up into the slot 8, Fig. 1, and flush with the upper surfaceof the sill 3.

12 is a rope or cord connected to the weight 11 and the bar 9 and passesover the pulleys 13, supported on their axles 13 and placed in thepocket or recess 13 Fig. 1.

14 is the fastening-point for the ropes 12 on the bar 9 and is placedbeneath the same, as shown, the point being below the center of thepulleys 13, so that the bar may come closely up and be held to the sill3.

WVhile the rope 12 is shown secured to the weight 11 by ring-bolts orscrew-eyes 15, I prefer to bore a hole through the weight near each ofits ends and cause the rope to pass through them, then tying a knot 16,Fig. 9. to prevent the rope from slipping through the holes, as shown.

The weight 11 is provided with holes through which pass the rods 17,secured to the floor timbers and at some convenient place under the sill3, and are for the pur ose of guiding the weight and preventing it omvibrating when the device is used in cars and on steamboats.

I show two rods in the drawings; but if the window is small one may besuflicient,-or the rods may be replaced by the bar or bead 18, Fig. 1,if desired, thus dispensing with the apertures 19, Fig. 7, in theweight, also the rods 17.

The weight 1] rests upon the blocks or bars 20 when the window is closedand also abuts upon the block 21 when the weight rises and the window isopen.

The elevator bar or carrier 9 is provided with shoulders 22, Fig. 8, soas it may not rise above the upper surface of the sill 3, as shown inFig. 1.

23 is a spring frame or bar bent to form a U-shaped figure and bearsupon two sides of the sash when it is being raised or lowered and uponits bottom portion when raised, the bottom part 23 of the bar or framebeing ex tended from the sash 5 for a handle or pull, as will bedescribed hereinafter. The free; ends of the bar or frame 23 terminatein coiled springs 24 of two or more convolutionsi and ending in a shortportion 25, which isl adapted to fit in bushings 26 in the top of thewindow-frame 4, as shown in Figs. 1 and 2. The lowerportion 23 of theframe or rod 23 is inwardly bent into a curve 27 and still fur-; therextended from the sash 5, as at 28, Fig. 5 3, for the purpose ofpermitting the hand to, be inserted to grasp the handle 29 for pullingthe sash inward so it may rest upon the ele vator bar or carrier 9 whenit is desired tol lower the window.

30, Fig. 5, is a modified form of spring ant may be used where it is notpractical to apply 1 the coiled springs shown at 24. j-

The lower portion of the sash 5 is provided. with two or more hooks 3].,bywhich it may be pulled from its position (shown in Fig. 1) 1 by meansof the lower portion of the bar or? frame 23 preparatory to opening thewindow.

32 represents stoppins'placed on the win-.j dow-frame or upon the beador stop 7, their function being to prevent the frame 23 from; beingpulled out too far, as the hooks 31 i leave the part 23 when the sashstarts to descene], and when the handle 29 is released the force of thesprings 24 cause the U-shaped; frame 23 to press against the sash 5 instriking alinement with the hooks 31 when the sash is again raised.

The sill 3 is provided with suitable grooves to. allow the hooks 31 topass through the same, though I do not show them, such being a. matterof construction and adaptation.

33 is a. pocket in the side members of the windowframe 4 for the springs24 and is a modification to be used when the windows of a. railway-caror steamboat are provided with transoms or where the upper portion ofthe window-frames areinaccessible.

The operation of the described mechanism is as follows: When the windowis closed, the lower part of the U-shaped rod-frame 23, is pulled towardthe inside of the car, saloon, or room by means of the handle 29, whichplaces the lower edge of the sash on top of the bar or carrier 9. Then adownward pressure of the sash carries. it squarely d own between thecarfacing and lifts the weight 11. During this action the lower portion23 of the U-shaped frame bears against the side members of the sash 5,which. holds the window down by friction and acts so asto preventrattling of the sash. To raise the window, the handle 29 is pulledslightly inward, causing the sash to rise fast or slowly by the weight11 and may be made to close entirely or partly open, as may be desired.When the window is to be completely closed and after it has risen as faras it will go, by releasing the handle 29 on the frame 23 the force ofthe springs 24 pushes the sash outward in the position shown in Fig. 1and may be subsequently opened without eifort, which is not usual withother windows in use by reason of imperfect joints, inadequate handholdsor pulls, and other defects.

Having described my invention, what I claim, and desire to secure byLetters Patent, is-

1. In an apparatus of the class described comprising a window-frame,facing-boards or housing, a sill having an elongated opening, a sashadapted to pass in said opening and between the facing-boards orhousing, a carrier or elevator bar adapted to close said opening in thesill when in a raised position, guides for the carrier, a weight adaptedto approximately balance the combined weight of the sash and thecarrier, pulleys disposed in a pocket under said sill and above thecarrier when in an elevated position, ropes or cords passing over saidpulleys and connected to said weight and the carrier, a stop block forsaid weight when raised, guide-bars passing through the weight, aU-shaped bent rod secured to the window-frame having springs at its freeends adapted to bear upon the sash, means for placing the sash upon saidcarrier or elevator bar by said springended rod, means for automaticallyraising the sash when said rod is released from the sash, and springmeans for removing the sash from said carrier or elevator barto the sillat an angle when the carrier-bar is raised.
